identifier' : not a function

The identifier is used as a function but not declared as a function.

The following sample generates C2063:

// C2063.c  
int main() {  
   int i, j;  
   j = i();    // C2063, i is not a function  
}  

Possible resolution:

// C2063b.c  
int i() { return 0;}  
int main() {  
   int j;  
   j = i();  
}
